android imageview onClick animation

Question

I guess this is kind of an odd question but I have tried setting onClicklistener on an ImageView and it has worked. But the problem is that the user cannot sense the click. I me

Answer 1

You'll want to use a drawable that contains different images for the different states you want to support. Here's an example:

<?xml version="1.0" encoding="utf-8"?>    
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@drawable/img_pressed" />
    <item android:state_focused="true" android:drawable="@drawable/img_focused" />
    <item android:drawable="@drawable/img_at_rest" />
</selector>

Name this file img.xml or something and put it in your drawable directory, then set your ImageView's image to img.xml. @drawable/img_at_rest is the original image you're trying to use, while @drawable/img_pressed and @drawable/img_focused are the images to use for their respective states. You can also use solid colors instead of images if it's appropriate for your use case.

anim/anim_item.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
  <alpha
    android:fromAlpha="0.0"
    android:toAlpha="1."
    android:duration="1000">
  </alpha>
</set>

And add:

myView.startAnimation(AnimationUtils.loadAnimation(context, R.anim.anim_item));

Answer 3

   <?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">

<alpha
android:fromAlpha = "1.0"
android:toAlpha = "0.5"
android:duration = "300">
</alpha>
<scale
android:fromXScale = "1"
android:toXScale = "0.9" 
android:fromYScale = "1"
android:toYScale = "0.9" 
android:pivotX="50%"
android:pivotY="50%" 
android:duration = "50">
</scale>
</set>

I don't know if this is the correct method but defining an animation as mentioned did the trick. Now we just have to give

public void onClick(View v) {
v.startAnimation(AnimationUtils.loadAnimation(Context, R.anim.image_click));
//Your other coding if present
}

in the OnClick method and the change will be visible...

Not sure if it works, but have you tried setSelected() http://developer.android.com/reference/android/widget/ImageView.html#setSelected(boolean)
